new and useful Improvements in Heaters,

of which the following is a specification.

My invention 1s an improved a1r heater, whlch 15 very economlcal 1n fuel consumption, and simple in construction.

Referring to the drawings which form a part of this specification:

Figure 1 is a top plan view of my heater.

Figure 2 is a sectional view taken on the line 22 of Figure 1.

Figure 3 is a sectional view taken on line 33 of Figure 1.

Referring more particularly to the drawings, the numeral 1 indicates the outer fresh air chamber of my heater and 2 the inner heated conduits. The walls of the outer chamber are spaced away from the conduits 2, and have a fresh air inlet pipe 3 in the bottom thereof, and a plurality of outlet vents A in the top wall, which are directed to the rooms to be heated.

Below the conduits 2 is positioned a combustion drum 5 which is supported from the floor of my heater. A burner '6 extends 3o horizontally into the drum 5 and an auxiliary air supply tube 7 extends into said drum below the burner and from the back of the heater. This additional air supply insures complete combustion of the fuel, Which might otherwise be wasted and makes a very hot flame. The flame from the burner 6 impinges upon a baffle plate 8 in the drum 5. Pipes 9 lead fromthe drum 5 to a circulating drum 10. The drum 10 has a semicircular baflle plate 11 positioned therein with the convex surface of the plate facing the pipes 9. Pipes 12 lead from the drum 5 to a circulating drum 13. A baffle plate 14 is positioned in the drum 13 in the same, manner as the plate 11 in drum 10. The

drums 10 and 13 are parallel to each other and above the combustion chamber 5.

Above the drums 10 and 13 and at right angles to them are two parallel drums 15 and 16. Pipes 17 and 18 connect the drum 10 and the drums 15 and 16 respectively, and pipes 19 and 20 connect the drum 13 and the drums 15 and 16 respectively. A semicircular baffle plate 21 is secured in the drum 15, the convex surface being downward, and a baffle plate 22 is similarly secured in the drum 16. A pipe 23 joins the drums 15 and 16 from which pipe extends the outlet vent 24:.

The products of combustion and heated air in passing through the conduits 2, that is the drums 5, 11, 13, 15 and 16, impinge upon the baflie plates in said drums and are thrown towards the walls of the drums Where the heat may be more readily taken up by the fresh air in the outer chamber 1 and then conveyed to the rooms.

Having described my invention, I claim:

1. A heater comprising an outer fresh air chamber and a heating chamber within said fresh air chamber, said heating chamber including a combustion drum, a plurality of circulating drums above the combustion drum, pipes connecting the combustion drum with each of the circulating drums, upper drums above the circulating drums and pipes connecting the upper drums and the circulating drums, a pipe connecting the upper drums and a pipe leading from the last mentioned pipe to an outlet.

2. A heater comprising an outer fresh air chamber and a heating chamber within said fresh air chamber, said heating chamber including a combustion drum, a plurality of circulating drums above the combustion drum, pipes connecting the combustion drum with each of the circulating drums, upper drums above the circulating drums, pipes connecting the upper drums and the circulating drums, a pipe connecting the upper drums, a pipe leading from the last mentioned pipe to an outlet and baffle plates in each of the drums whereby the heat may chamber and a heater Within said fresh alr chamber, a cylindrical co'mbustlon drum having burner there n, a serial-cylindr cal extending outward y and above the coincal drums, said upper drums each having a semi-circular bafiie plate therein, perpen- 10 dicular pipes eopnecting the upper drums and die cirtiul zi tifig' cjt li hdiic'al E and an outlet li'dr the upper drums.

Ifite'stiinony whereof I afiix my signature.

JAMES A; CLYMER.
